Abstract

The invention relates to the technical field of safety valves, in particular to a pressure-reducing safety valve. The pressure-reducing safety valve comprises a valve seat, a valve sleeve and a valve element; the valve seat is fixedly connected with the valve sleeve; and the valve element is arranged in a cavity of the valve sleeve and can perform reciprocating motion in the extension direction of the cavity of the valve sleeve, so that a cavity of the valve seat is communicated or disconnected with the cavity of the valve sleeve. By means of the pressure-reducing safety valve, gas can be discharged rapidly; safety of a hydrogen-oxygen mixture device or a hydrogen-oxygen mixture pipe is guaranteed; and the pressure-reducing safety valve is high in reliability.

Description

technical field [0001] The invention relates to the technical field of safety valves, in particular to a decompression safety valve. Background technique [0002] The process in which water is electrolyzed by direct current to generate hydrogen and oxygen is called electrolysis of water. When current passes through water, hydrogen is formed by reducing water at the cathode, and oxygen is formed by oxidizing water at the anode. Hydrogen is produced approximately twice as much as oxygen. [0003] Hydrogen has been listed as a potential clean energy fuel due to its high energy density and zero emissions (does not emit any greenhouse gas). At the same time, hydrogen fuel can drive various electronic devices and electric vehicles through hydrogen fuel cells. With the rapid development of hydrogen fuel, electrolytic hydrogen production is gradually stepping into industrialization to replace the traditional steam reforming hydrogen production method to eliminate the dependence on...
